Type

Popular display types include In-Plane Switching (IPS), Thin Film Transistor (TFT), and Active-Matrix Organic Light-Emitting Diode (AMOLED). Colors are brighter in AMOLED displays and blacks are darker. IPS screens are cheaper to produce and display natural colors while AMOLED colors tend to be over-saturated. IPS displays the whites better but has poor viewing angles while whites in AMOLED tend to be little bit yellowish but the viewing angles are better. IPS is preferred by photographers for the natural colors while AMOLED is preferred for everyday regular users. IPS improves on the old TFT technology like Super AMOLED improves on AMOLED

Tests

Audio Quality

The audio quality of the phone is determined based on the signal-to-noise ratio, the higher the value, the better, and stereo crosstalk which is a measurement of the isolation between the right and the left audio channels. The lower the value, the better in this case as a high value means there is a leakage of signal from one channel to the other and the stereo effect would be decreased. Both values are reported in Decibel (dB) unit

Noise -91.6dB / Crosstalk -90.4dB

Display

The most important test for examining the quality of a phone display is the Contrast Ratio which is the difference between the brightest white and the darkest black of the display. A good screen should display the bright colors as bright as possible and the dark colors as dark as possible. For the Contrast Ratio to be tested accurately and fairly, it should be under the sunlight as the sunlight heavily influences the colors so if a display keeps a high Contrast Ratio value while the sunlight is projected on it, that means it's a pretty much good display

Loudspeaker

The loudspeaker of the phone is tested for the loudness of voice, pink noise, and ringing tones. Pink noise is the background noise you encounter a lot in everyday life like the sound of a fan spinning or a moving train. The values are measured in Decibel (dB) unit and the higher the values, the louder and better the loudspeaker is

Performance

What is the Basemark score(s) of the phone? Basemark is the most popular benchmarking tool in the world for the evaluation of the performance of a cell phone. Basemark OS II is the overall performance score of the phone on a systemic level while Basemark X evaluates the gaming and graphics performance of the phone. The higher the value, the better
